FIELD OF THE INVENTION

The present invention relates to systems and methods for managing andpublishing content and more specifically to managing and publishingmanaged content.

BACKGROUND

A content management system is a system configured to enable themanagement and publishing of content stored using the content managementsystem. Content management systems organize and store a variety ofcontent, such as documents, image data, video data, and audio datautilizing a back-end storage system. Content management systems alsoprovide functionality to centralize the publishing of those documents,such as via one or more web sites. By providing centralizedfunctionality for the publishing of documents, a content managementsystem provides a convenient way to host and manage a variety of websites from a single back-end storage system.

The Internet is a global system of interconnected computer networks.Varieties of services are provided on the Internet, including websites.Websites include a variety of content, such as text, pictures, audiodata, video data, and other interactive content. Web sites are typicallyhosted using content servers and a web browser is an application thatenables a user to receive, view, and interact with a websites hosted oncontent servers. A variety of web browsers are commonly used to viewwebsites, including Internet Explorer from Microsoft Corporation ofRedmond, Wash. and the Chrome browser from Google, Inc. of MountainView, Calif.

Many documents, including web pages within a website, are written usingthe Hypertext Markup Language (HTML). A HTML document contains a set ofnested tags. HTML tags include data stored in the tag, either as aproperty of the tag or between an opening tag and a closing tag. Webbrowsers do not display the HTML tags; rather, web browsers areconfigured to parse a HTML document and render one or more web pagesincluding the information stored in the HTML tags. Cascading StyleSheets (CSS) are used to describe the formatting and display of adocument when it is rendered. CSS can be used to describe the formattingof a variety of documents, including HTML documents and other documents,such as documents written using the Extensible Markup Language (XML). Asingle document can have a variety of associated CSS, so that thedocument can be rendered in a variety of ways depending on thecapabilities of the device used to display the document. For example, aHTML document can be rendered with one format in a web browser on adesktop computer using a CSS designed for a desktop browser, while thesame HTML document can be rendered in a second format in a web browserrunning on a mobile phone using a second CSS designed for a mobilebrowser.

Many web pages utilize scripts in order to provide flexibility in thecreation and display of a web page. Scripts can be written in a varietyof languages, including JavaScript by the Mozilla Foundation of MountainView, Calif. and ECMAScript, standardized as ECMA-262 by ECMAInternational of Geneva, Switzerland. Web browsers are configured toparse and execute scripts contained in web pages. These scripts cancontrol the appearance of a web page, customize the content according tothe preferences of a user viewing the web page, and allow for data to bereceived using the web page. Scripts can be server-side, where thescript is run on a content server, or client-side, where the script isrun using the web browser receiving the script.

In a variety of embodiments, the transmitted (516)content is a version of the located (514) managed content generatedutilizing processes similar to those described above. In severalembodiments, the transmitted (516) content is the located (514) managedcontent.

By way of example, by basing the version of the managed content toprovide on the time of the request for content, a version of the located(514) managed content can be developed for events on particular days andtimes (such as holidays and other noteworthy events) in advance of theevent and automatically presented in response to obtained (512) contentrequests on those identified days and times without taking anyadditional action. When the indicated time and/or event has ended, theoriginal version of the content (or a newer version) is automaticallytransmitted (520) in response to obtained (512) content requests withoutany additional work necessary to either update the managed content orroll the managed content back to a previous version. As a secondexample, multiple variants for the same piece of managed content can becreated in order to test the relative performance of the variants of themanaged content. The obtained (510) content version decision dataindicates the variants of the managed content to present and the desiredcriteria to transmit (516) a particular version of the located (514)managed content. In several embodiments, the criteria can include (butare not limited to) presenting certain versions of the located (514)managed content based on geolocation data indicating the location of thedevice from which the content request was obtained (512), the time atwhich the content request was obtained (512), and/or the number of timeseach version of the managed content has been transmitted (520). In thisway, the obtained (510) content version decision data can be utilized toperform comparison testing of multiple versions of located (514) managedcontent, geographic-based targeting of content, and/or time-basedtargeting of content.

Although a specific process for presenting alternative versions ofmanaged content is described above with respect to FIG. 5, any number ofprocesses can be utilized in accordance with embodiments of theinvention. Methods for associating performance information with versionsof managed content in accordance with embodiments of the invention arediscussed below.

Tracking Managed Content Performance

It is often useful to track the performance of various versions ofmanaged content. The tracked performance data can be associated with theappropriate versions of the managed content and used to identify thoseversions that perform well and/or poorly. Versioned content managementserver systems in accordance with embodiments of the invention areconfigured to receive and store performance data associated with variousversions of managed content. A process for associating performanceinformation with one or more versions of managed content in accordancewith embodiments of the invention is illustrated in FIG. 6. The process600 includes obtaining (610) performance information. Managed content islocated (612) and content version metadata is updated (614).

In a variety of embodiments, performance information is obtained (610)from content delivery server systems providing content to contentdisplay devices. In many embodiments, performance information isobtained (610) from a client display device. In several embodiments, theperformance information is obtained (610) based on comparison testing ofversions of managed content utilizing processes similar to thosedescribed above. In a number of embodiments, the performance informationcontains engagement data. Systems and methods for determiningperformance information for content that can be utilized in accordancewith embodiments of the invention are disclosed in U.S. patentapplication Ser. No. 13/792,855, titled “Systems and Methods forCategorizing and Measuring Engagement with Content” and filed Mar. 11,2013, the disclosure of which is hereby incorporated by reference in itsentirety. In several embodiments, locating (612) managed contentutilizes the obtained (610) performance information to identify themanaged content and/or a version of the managed content. In a variety ofembodiments, updating (614) the content version metadata includesassociating the obtained (610) performance information with the located(612) managed content and/or one or more pieces of content versionmetadata associated with the located (612) managed content.

A specific process for tracking the performance of different versions ofmanaged content is described above with respect to FIG. 6; however, anynumber of processes can be utilized in accordance with embodiments ofthe invention.
